fast_flows 0.0.3

A light, modern and powerful Flutter framework combining state management, dependency injection, and route management - inspired by GetX but with a cleaner API.

/// Fast Flows Framework Example App
///
/// This example demonstrates all the features of the Fast Flows framework:
/// - Dependency Injection with Flow.put/Flow.find
/// - Reactive state management with Rx types and Flx widget
/// - Route management with Flow.to/Flow.toNamed
/// - Logic/State/View separation pattern
/// - Light/Dark theme switching
/// - Custom app icon (flows.png)
///
/// Supports: Android, iOS, Web, Windows, macOS, Linux
